New Attacks Against 4G, 5G Mobile Networks Re-Enable IMSI Catchers


At NDSS Symposium 2019, a group of university researchers yesterday revealed newly discovered cellular network vulnerabilities that impact both 4G and 5G LTE protocols.

According to a paper published by the researchers, “Privacy Attacks to the 4G and 5G Cellular Paging Protocols Using Side Channel Information,” the new attacks could allow remote attackers to bypass security protections implemented in 4G and 5G, re-enabling IMSI catching devices like “Stingrays” to intercept users’ phone calls and track their location.

Here below, we have described all the three attacks, how they work, what are their impacts, and why you should be concerned about these attacks.
